Title: Method and apparatus for automatically extracting and retracting an antenna in a wireless telephone
Inventor: LEE HAN-SANG
IPC: H01Q1/24
Filed: 1997-10-27
Granted: 2000-07-21
Abstract: When an operation such as opening or closing of a front cover or a key operation of communication-start or communication-end occurs, a controller acquires information for extraction or retraction of an antenna.  Basing on the above information, the controller controls a motor driving by intermittently supplying motor driving signal by which the motor can rotate clockwise or counterclockwise during a preset time necessitated for fully extracting and retracting an antenna.  While motor driving, if a blocking force applied to an antenna, the controller repeatedly stops supplying of the driving signals to the motor for a predetermined interval and then resumes supplying the signals.  A gear unit is tightly coupled in a body with the motor, receives a rotating force from the motor shaft, and extracts and retracts an antenna.  In addition, there is further provided a fixing element for fixing the motor and the gear unit to an antenna housing, which is able to absorb external impact transferred to the motor and the gear unit through an antenna and to absorb a vibration of the motor.  When a front flip cover is opened or a communication-start key is pushed by a user to use a wireless telephone, the antenna is automatically extracted from the antenna housing, while when the front flip cover is closed or a communication-end key is pushed, the antenna is automatically retracted into the antenna housing.

Title: Solid gel membrane
Inventor: CHEN MUGUO
IPC: G02F1/15
Filed: 2000-02-24
Granted: 2001-11-11
Abstract: A highly conductive polymer based solid gel membrane is disclosed. The membrane is especially well-suited for use in such electrochemical devices as metal/air, Zn/MnO2, Ni/Cd and hydrogen fuel cells, as well as in electrochromic devices such as smart windows and flat panel displays. Furthermore, in rechargeable electrochemical cells, the solid gel membrane is highly effective for use as a separator between the anode and charging electrode. In accordance with the principles of the invention, the highly conductive membrane comprises a support or substrate and a polymeric gel composition having an ionic species contained in a solution phase thereof. The polymer-based gel is prepared by adding an ionic species to a monomer solution followed by polymerization. After polymerization, the ionic species is embedded in the polymer-based gel where it remains. The ionic species behaves like a liquid electrolyte, while at the same time, the polymer-based solid gel membrane provides a smooth impenetrable surface that allows for the exchange of ions. An advantage of the novel membrane is that its measured ionic conductivity is much higher than previously observed in prior art solid electrolytes or electrolyte-polymer films.

Granted: 2001-11-11
Abstract: A memory processing method is able to load an executable object code complied from a source code into memory with defects. The method comprises, first, arranging a plurality of pre-coded object code corresponding to the source code, each pre-coded code having at least one code jumping address range; next, testing the memory to find the defected address therein, thereby, based on the test result, loading the executable object code with matched code jumping address range selected by the system from the pre-coded object code for loading into the memory. Because the jumping address range can cover the defected address in the memory, the defected memory cells in the memory will not influence the execution of the loaded program.
